AGETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Application filed January 26, 1911. Serial No. 604,829.

To all whom it may concern.

Be it known. that I, GARD W. S1rrrrr, a citizen of the United States, residing at Markle, in the county of Huntington, State of Indiana, have invented certain new and useful Improvements in Acetylene-Gas Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such asgwill enable. others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in acetylene gas generators of that type generally known as the carbid feed type.

The principal object of this invention is to provide a generator having a novel construction wherebygas may be generated in unusually large quantities.

Another object of the invention is to .provide a novel construction of valve for permitting the egress of the carbid from its chamber.

A still further object of the invention is to provide a generator having its parts arranged to permit of the same being easily removed from the casing.

Another objectof the invention is to provide a generator of the class described which is simple in construction, positive in operation, and extremely cheap to manufacture.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated. in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of'the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a vertical sectional view through the generator, parts thereof being in elevation, Fig. 2 is a secline 22,of Fig. 1, Fig. 3 is an enlarged sectional view of the valve nic(.'lianism.-

Like reference numerals designatecorrcspending parts in all the figures of the drawings.

Referring to the drawings the invention comprises a casing 5, which is preferably formed of concrete. This casing is provided with a bottom 6 and an open upper end 7. A socket 8 is formed in the Wall and opens at the top edge thereof. Disposed within the said socket is one end of a Patented Apr. 16, 1912.

crane 9, the free-end of the crane being preferably curved and provided with a pulley 10 of ordinary construction. A top 11 is normally positioned on the casing and may be lifted therefrom or positioned therein by means of a cable 12 connected to theto and passing over said pulley 10, as will be readily understood. The other end of, the cable 12 is connected having the usual handle 14 thereon.

Disposed within the casing 5 and'spaced from the inner face thereof is a bell '15 having a top 16. Secured to the top by any suitable means are spaced rollers 17 which bear against the inner face of the casin A positively actuated valve 19 of any pre ferred construction is located on the top 16 of the bell for permitting the egress of air from the bell when the latter is being positioned within the casing. Secured to the top 16 by suitable means is a bail 20 by means of which the said bail can be readily lifted out from within the casing- Disposed within the bell 15 is an inverted frusto-conical carbid chamber 21 having an outlet opening 22 at its lower end. This chamber is supported a suitable distance above the bottom 6 of the casing'by suitable standards 23. The upper end of the chamher is closed by a top 24 and formed in the wall of the chamber below the said top is a plurality of openings 25 through which the gas mayenter as will be hereinafter more fully explained. A suitable inlet opening for the carbid is formed in the top 24 and associated therewith is a closure cap 26. Located within the chamber 21 and contiguous to the opening 22 thereof is a valve-seat 27 is adapted to be seatupon which a valve 28 ed. This valve 28 is provided with-a stem 29 which projects through a suitable opening 30 formed in the'top 24, and terminates in a point some distance above the said top. Extending transversely through the stem 29 above the top is a pin 31, which is received into elongated openings 32 ,formed in the leverarms 33-33. These lever-arms are pivotally connected upon suitable brackets 34-34 and have their opposite ends suitably connected to Weights 35-35. At this point it will be observed that on account of the elongated slots 32 in the lever arms, the said levers will be permitted to be osclllated upon movement in either direction of the to a ratchet-drum 13,

valve stem 29. Disposed within the said i cured to the members 52 and by rivets or chamber 21 is a deflector 36 of any preferred construction. This deflector is preferably disposed around the valve stem 29 and terminates short of the walls of said chamber.

A transverse pin 37 is secured to the stem 29 above the valve 28 and below the deflector 36 and has its opposite ends projecting from said stein. A secondary valve is disposed within the chamber belowthe transverse pin 37, and consists of two semi-circular plates 3939 which are respectively provided with partial recesses 40-40 which coact to tightly fit around the valve-stem 29. These sections are connected to the chamber 21 by means of hinges 41, which are respectively arranged in a plane at right angles to the plane of the meeting edges of said sections. Links 42-42 are respectively pivotally connected at both ends to a section 39, and the corresponding end of the transverse pin 37. It will thus be observed that as the valve stem 29 is depressed the links 42 will cause the sections 39 to be lowered in unison, and that upon theupward movement of the valve stem the said sections will be closed in unison. It will also be noted that when said sections are in the open position, they, together with the deflector 36, will cause the carbid to be read- -ily broken as it passes through the valve opening 22. By this means the said valve opening will be prevented from becoming clogged as will be readily understood. The weights 35 are adapted to normally retain the valve 28 against the seat 27. p

' Extending from the upper portion of the chamber 21 and preferably in alineinent with the openings 25, is an outlet pipe {4-3 which extends downwardly within the bell 15 as shown by reference numeral 44. The pipe then extends outwardly through the casing 5, as shown by 4b., Disposed within this section l6 is a turning-plug 47 of any 5 I stem tor operating the said secondary valve suitable construction, and connecting the said plug is an operating rod-1S having a handle lttat its upper end By means ot this handle the said block can be actuated and. thereby regulate the egress ot' the gasv Seated upon the bgttom 6 ot the casing '47 is a receiver designated as a whole by the referencenumeral,50. This receiver is composed of three nested members 51-52 and 53respectively, the member 51 being provided with a bottom 54. The members 52 and 53 are open ended and are disposed in stepped relation and are of dill'erent sizes. Secured to the member near the upper end thereof is a plurality of brackets 55 having l'astening means :36 connected thereto, said means operating in conjunction with suitable staples :37. Thus it will be observed that the nu-mber 52 is detaehably secured to the m mber ill and is held in spaced relation thereto. Brackets 58 are rigidly other suitable means. Thus it will be observed that these brackets 58 rigidly connect the members 52 and 53 together so thatupon release of the hasps 56 the said members can be separated from the member 51. A

bail 59 is connected to the upper end of the center member 53, and by-hieznis of this ,bail

positioned or withdrawn as may be desired. In the operation of the generator? the carbid is placed within the chamber/21', and

waterv is of course poured into the casing] 5 to a point below the valve opening 22. The bell 15 is then positioned, and as the same makes its downward movement, the valve 19 is opened, thereby permitting the egress of air from the bail.. The valve' is then closed, andthe top 16 will contact with the upper end of the valve stem 29,1thereby' actuating the double-hinged valve 39, and the,

valve 28. pass through the opening '22 and, into the water. As' 'a result gas w'illbe' generated which will cause the bell 1,5 crises A sithe A quantity ofcarbid will then weight of the bell 15 is lifted 'froi 'tlievalve witha casing, of a gas-bell disposed therein,
